A masterpiece of Gothic architecture, the Doge’s Palace is an impressive structure composed of layers of building elements and ornamentation, from its 14th and 15th century original foundations to the significant Renaissance and opulent Mannerist adjunctions. The structure is made up of three large blocks, incorporating previous constructions. The wing towards the St. Mark’s Basin is the oldest, rebuilt from 1340 onwards. The wing towards St. Mark’s Square was built in its present form from 1424 onwards. The canal-side wing, housing the Doge’s apartments and many government offices, dates from the Renaissance and was built between 1483 and 1565.
